we have the function

$E=\sin \frac{\pi}{14}t$

Part a

For t=7

substitute in the given function

$\begin{gathered} E=\sin \frac{\pi}{14}7 \\ E=1 \end{gathered}$

For t=14

$\begin{gathered} E=\sin \frac{\pi}{14}14 \\ E=0 \end{gathered}$

For t=21

$\begin{gathered} E=\sin \frac{\pi}{14}21 \\ E=-1 \end{gathered}$

For t=28

$\begin{gathered} E=\sin \frac{\pi}{14}28 \\ E=0 \end{gathered}$

For t=35

$\begin{gathered} E=\sin \frac{\pi}{14}35 \\ E=1 \end{gathered}$

Observation: The values of E varies from -1 to 1, including the zero

Part B

Remember that

The Period goes from one peak to the next

Period=2pi/B

B=pi/14

Period=(2pi)/(pi/14)=2pi*14/pi=28

<h2>the period is 28 days</h2>

How would you convert a mass in centigrams to a mass in milligrams??

const2013 [10]

First let's start with the relationship between grams and centigrams and grams and milligrams.

1 gram = 100 centigrams
1 gram = 1000 milligrams

Because these two equations are equal, we can rewrite our equation as 100 centigrams = 1000 milligrams.

Now we divide by 100 to simplify our equation to 1 centigram = 10 milligrams.

With this simplified equation we see that we multiply the number of centigrams by 10 to find the equal number of milligrams.
